PLOWSHARE,

Application filed may 21, 1926, Serial No. 116,607, and in Germany`iepternber 30, i925.

T he attachment of plowshares to the plow wherein the share is of Vsection and is slid on to the correspondingly formed lower portion ofthe plow-breast, is known. The

mode of attaching a plowshare of V section to a plow-breast, which formsthe subject of the present invention differs by the provision of agroove and feather connection from the known mode of attachment. Theplowshare is slid on in the direction of the working pressure, and atthe end of the fitting groove an abutment is provided, which limits thesliding-on displacement of the share and provides same with a firmseating.

An example of the subject of the invention is illustrated on theaccompanying drawing, in which z- Fig. l is a side elevation of aplow-breast and attached plowshare.

Fig. 2 is a side elevation on a larger scale of the lower portion of theplow-breast with the share not quite brought home to its seating, and

Fig. 3 is a transverse vertical section on 25 line 3-3 of Fig. 2.

The part a of V section and provided with a cutting edge al, may bedirectly attached as a plowshare to the plow-breast b of the plow or canbe attached as a' cutter to a so plowshare body portion secured to theplowbreast. For the purpose of securing the share a, the plow-breast b,-or the. plowshare body portion as the case may be, is shouldered down toa Wedge section at its lower :is border d and is formed on one or bothsides with a longitudinal groove c. Along the inside of the top of the Vsection share a is provided with a rib e, which easily lits in ythegroove c. At the rear end of the wedge section border d, the groove c isclosed and at the rear end of the share a the rib is interrupted, .sothat, when the V section of share a is thrust home on the wedge sectionborder (l of the plow-breast b, or on an additional share body portion,the rib e sliding longitudinally in the groove c, the rear end f of therib e ahuts firmly against the end g 0f the groove 0 and preventsfurther displacement of the share in the direction of the workingpressure. By displacing the share in the reverse direction it can beeasily and readily removed from the plow-breast for sharpening 0rreplacement. l

rlChe present invention is applicable to the shares of potato diggers,cultivators and the like as well as to plows proper.

l. A plowshare comprising a body member having a lower portion ofreduced thickness extending from heel to point thereof, one side of saidportion being provided with a longitudinal groove extending from thepoint of said portion and terminating adjacent to the heel thereof, anda cutting member having a grooved portion slidably mounted on saidreduced portion of the body member in the direction of the line ofdraft, said cutting member being provided with a rib engaging the groovein the reduced portion of the body member.

2. A plowshare comprising a body member having a lower portionwedge-shaped in cross-section, said portion being provided with a.longitudinal recess in one of its sides extending from its forward endto a point near its rear end and terminating at the latternamed end in ashoulder, and a vcutting member adapted to be slid onto and olf saidbody member at its forward end, said cutting member having in its upperpart a longitudinally extending V-shaped groove to receive and engagethe wedge-shaped portion of the body member, the walls of said groovebeing of substantially equal height and one of said walls being providedwith a. longitudinally extending rib to engage the said recess in thewedge-shaped portion of the body member, the rear end of the ribterminating in advance of the rear end of the cutting member and adaptedto abut 90 against the aforesaid shoulder.

In testimony whereof I affix my signature.
